Basics of Calculus, continued (1 of 2: Sum of functions)

[@s4ad0wpi]

Would have renamed h(x) to make it less confusing

[@IlValentino100]

u,v instead of g,h. much less confusing.

2:27 See the students reaction.

[@DubioserKerl]

At the time of the lecture, have you had already proven that lim(a(x)+b(x)) = lim(a(x)) + lim(b(x))? Because that fact is needed for the transition between the penultimate and the last line of your proof...

[@沈博智-x5y]

proving this seems to require epsilon delta and that stuff is beyond high school maths.

[@shaikhsaad9463]

Sir please make a lecture on laplace

[@piggo5645]

So f’(x) of that last one you wrote on the board would be 4x^3 + 6x + 1?

[@okraschoten681]

Yes

[@krukowstudios3686]

You got it

[@treedri9365]

I'm so fascinated of math. But people always say:"No you can't understand math. You're just 15 years old." I'm so tired of these sentences. What should I do?

[@Adam-cn5ib]

That was something that trapped me when I was 15 years as well. I ended taking an education less focused on math and regretting it 5 years later. Pursue what you believe is meaningful work and only focus on your own intuition, only. Humans are apes and we do seek for social connections. One way people are doing that is to adapt to each other's needs. If someone hates math, then that is likely to spread to the other group as they "socially" adapt to things they like.

[@AriaHarmony]

I agree with Cryptomang, study what you want to study, not what others think you should. People come and go, but you will always be around to witness how your decisions effect your own life. Also just because someone else couldn't understand math at 15 doesn't mean that *you* can't. This is the golden age of knowledge, there are many awesome people like Eddie that post educational materials on the internet, you can almost always find someone who explains it even better :)

[@dipankarhazra6083]

Sir can you please explain wheather zero positive or not?

[@AriaHarmony]

Zero is neutral. Not positive or negative. One explanation is: If you add a positive number the value increases. If you add a negative number the value decreases. But if you add 0 the value doesn't change, because it's neutral. This is actually called "the identity property of addition".

[@RikyPerdana]

Pair up the geez, Geez!!

[@UneCleUSB]

Poor explanation imo
